4 Claims.

This invention appertains to new and useful improvements in anti-skiddevices for vehicle wheels.

The principal object of the present invention is to provide an anti-skiddevice which can be readily attached to automobile tires in order toincrease traction in snow and on ice and to prevent skidding on wet andslippery pavements.

Another important object of the invention is to provide an anti-skiddevice of the character stated which is constructed in a simple andinexpensive manner, and which can be taken apart for the purpose ofrepair and replacement of parts when desired.

These and various other important objects and advantages of theinvention will become apparent to the reader of the followingspecification.

In the drawings:-

Figure 1 represents a side elevational view of the device.

Fig. 2 is a top plan view.

Fig. 3 is a fragmentary bottom plan view.

Fig. 4 is a fragmentary perspective view showing the band with therubber unit thereon.

Fig. 5 is a perspective view showing the cap plate and one of the bridgepieces.

Fig. 6 is a perspective view of one of the transverse calks.

Fig. 7 is a sectional view on line '!1 of Fig. 1.

Fig. 8 is a perspective view of the locking key.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 represents the elongated band which may be ofreinforced fabric, leather, or any other suitable material, and this isprovided at its ends with barrel-like constructions 6 through which tiemembers can be disposed.

As is shown in Fig. 4, the intermediate portion of this band 5 isprovided with cut away portions 1 at each of its longitudinal edgeportions as is the neck portion 8 of the calk assembly generallyreferred to by numeral 9. This assembly consists of the two rubberblocks l0l0 connected by the neck 8 which has the reduced portioncoincident with the cut away portions 7 of the band 5.

Numeral H represents a cap structure having the depending side flangesl2. This cap H is provided with longitudinal slots I3 therein whichextend over the reduced portion of the neck 8 and the cut-away portionof the band 5. Rectangular shaped calks It provided with dependingflange members [5 are pro vided, and these flange members l5 depend thruthe slots 13 and reduced portion of the neck 8 as well as through thecut away portion I of the band 5, and the lower portions of the insidesurfaces of these flanges l5 are provided with longitudinally extendinggrooves l6 for receiving the longitudinal edge portion of the lock platel7. When the flanges l5 are depending through the cap II in the mannershown in Fig. '7, the transversely arcuate looking plate I? can beinserted between the lower portions of the flanges l5 and the edgeportions of the plate engaged into the grooves it. This locking plate I!being of ductile material, can then be fed upwardly so that the edgeportions of the plate will entirely engage into the grooves It, thuspreventing the calks l4 from being displaced from the cap H.

An opening 18 is provided down through the cap H, neck 8 and band 1, sothat when desired, a tool can be inserted through the assembly andpunched against the key plate I I to remove the same from its lockingposition shown in Fig. 7, that is when repair or replacement of parts isdesired.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. An anti-skid device comprising a band, a cap secured to theintermediate portion of the band, said band having its longitudinal edgeportions reduced at the caps, said cap being provided with longitudinalslots therein, overlying the cut away portions of the bands, calkmembers pro vided with depending flanges disposed through the slots andcut away portions of the band, and a locking key between the saidflanges at a point underlying the band.

2. An anti-skid device comprising a band, a cap secured to theintermediate portion of the band, said band having its longitudinal edgeportions reduced at the caps, said cap being provided with longitudinalslots therein, overlying the cut away portions of the bands, calkmembers provided with depending flanges disposed through the slots andcut away portions of the band, a locking key between the said flanges ata point underlying the band, said locking key consisting of a ductileplate primarily of arcuate shape, said flanges being provided withgrooves on their opposed faces to receive the plate when it is flattenedout against the lower side of the band.

3. An anti-skid device comprising a band, a cap secured: to theintermediate portion of the band, said band having its longitudinal edgeportions reduced at the caps, said caps being provided with longitudinalslots therein, overlying the cut away portions of the bands, calkmembers provided with depending flanges disposed through the slots andcut away portions of the band, a locking key between the said flanges ata point underlying the band, said locking key consisting of a ductileplate primarily of arcuate shape, said flanges being provided withgrooves on their opposed faces to receive the plate when it is flattenedout against the lower side of the band, said caps and band beingprovided with registering openings through which an instrument can bedisposed for displacing the plate from the flanges.

4. An anti-skid device comprising a band, a cap secured to theintermediate portion of the band, said band having its longitudinal edgeportions reduced at the caps, said caps being provided with longitudinalslots therein, overlying the cut away portions of the bands, calkmembers provided with depending flanges disposed through the slots andcut away portions of the band, a locking key between said flanges at apoint underlying the band, and a calk assembly comprising a pair of calkmembers, a neck connecting the calk members, said neck being disposedbetween the cap and the band, said calk members being disposed beyondthe ends of the cap.
